Answer:

Animals have adapted to the harsh weather conditions and long winters of the tundra.

Animals migrate to eat insects that live there year round.

Many animals in the tundra hibernate during the long, cold winter months.

Animals are most active in the short summer as the snow melts and shallow wetlands form.

Living organisms in any biome interact through a variety of relationships. Organisms compete for food, water, and other resources. Predators hunt their prey. Some organisms coexist in mutually beneficial relationships (symbiosis), while others harm organisms for their own benefit (parasitism). Still others benefit from a relationship that neither helps nor harms the other organism (commensalism).

Animals found in the Arctic tundra include herbivorous mammals (lemmings, voles, caribou, arctic hares, and squirrels), carnivorous mammals (arctic foxes, wolves, and polar bears), fish (cod, flatfish, salmon, and trout), insects (mosquitoes, flies, moths, grasshoppers, and blackflies), and birds (ravens, snow buntings, falcons, loons, sandpipers, terns, and gulls). Reptiles and amphibians are absent because of the extremely cold temperatures. While many of the mammals have adaptations that enable them to survive the long cold winters and to breed and raise young quickly during the short summers, most birds and some mammals migrate south during the winter

You have a plant with yellow seeds, which express a dominant phenotype. How would you determine the plant's genotype? Conduct a
Archy [21]
The answer is <span>Conduct a test cross with a purebred recessive plant. 

</span>

Test cross is the cross between an organism with unknown dominant genotype and an organism with known recessive genotype.

<span>Since dominant trait results from a dominant allele, the test cross can determine if an unknown genotype is heterozygous and homozygous dominant. </span>

If A is dominant allele, and a is recessive allele, then AA is dominant homozygote, Aa is a heterozygote, and aa is recessive homozygote.

<span>According to the Punnett square, if all of the offspring are heterozygote (Aa), then unknown genotype is dominant homozygous (AA). If half of the offspring are the heterozygote, and the other half are recessive homozygote, then the unknown genotype is heterozygote (Aa).</span>

Ksenya-84 [330]

Answer:

The correct answer is d. Oxygen

Explanation:

Phytoplanktons are responsible for the fixation of approximately half of the global carbon therefore seawater has high CO2 concentration which is required by phytoplanktons to make their food.  

They are the primary producers of oceans and they are responsible to support the food chain of oceans. Factors that can limit their growth are mainly sunlight and nutrients like phosphorus, nitrogen, etc.

As phytoplanktons are photosynthetic they release oxygen itself as a byproduct therefore oxygen is not a limiting factor to phytoplanktons. So the right answer is d.

Is there a picture with this question? It seems like there's background information which isn't being shown here.

Pedigrees are basically a map of alleles for family trees
 
                   ______Person1 -- Person2_____
                  I                I                  I                 I
        __Person3_   Person 4     Person5    _Person6___

   Person7 Person8                 Person9   Person10  Person11

And under everyone's name you write their alleles.

Punnett squares give the probability of someone having genes based on their parents' genes.
